WINDMILL-CONTROLLING MECHANISM.

Specification of Letters Patent.

Application filed September 13, 1912.

Patented Mar. 18, 1913. Serial No. 720,238.

To all whom it may concern:

Be it known that I, JAMES F. SMITH, a citizen of the United States,residing at Phoenix, in the county of Maricopa and State of Arizona,have invented new and useful Improvements in \Vindmill-ControllingMechanism, of which" the following is a specification.

My invention is an improved automatically operated mechanism forstopping and starting a wind mill and to cause a wind mill and a pumpoperated thereby to maintain a constant level of water in a tank, theinvention consisting in the construction, combination and arrangement ofdevices hereinafter described and claimed.

In the accompanying drawings :Figure 1 is an elevation of a wind millprovided with a controlling mechanism constructed in accordance with myinvention. Fig. 2 is a detail vertical sectional View of the wind millcontrolling mechanism on a larger scale.

For the purposes of this specification, a wind mill is indicated at 1 inFig. 1, provided with a vane 2 to throw the wind mill into and out ofthe Wind and also provided with a lever 3 Which is connected to the vaneby means of a rod 4. A weight vessel 5 is suspended from the lever 3 bya rod 6 and moves between vertical guides 7 and is provided in itsbottom with an opening 8 and an upwardly opening valve 9 to close thesaid opening. A locking dog or detent 10 is arranged in one of theguides 7 and is connected, as at 11, to a locking and releasing lever 12which lever is fulcrumed as at 13 and has a tappet 14 which is arrangeddirectly in vertical alinement with the valve 9.

A pump is indicated at 15 which pump is operated by the wind mill, theusual pump operating rod or connections 16 being employed and this pumpdischarges into a tank 17. A pipe 18 leads from the tank at a suitablelevel and is arranged to discharge into the weight vessel 5. A float 19is movable in the tank and is connected by a cord 20 to the locking andreleasing lever 12, the said cord passing over a suitable direction pul--ley 21.

The operation of my invention is as follows: When the weight bucket 5 isempty,

the vane or controlling element of the wind .mill to which the saidweight bucket is connected through the instrumentality of the lever 3,rod 4 and rod 6 puts the mill in operation, thereby causing the pump tooperate and to supply water to the tank 17 When the water reaches therequired level in the tank 17, water flows from saidtank through thepipe 18 and is discharged into the weight vessel 5, the valve 9 of saidweight vessel being normally closed and the water being, hence,accumulated in the Weight vessel. WVhen the weight vessel becomesfilled, its weight becomes such as to put the wind mill out of gear andcause it to operate the vane or controlling element opening 8 and raisesand opens the valve 9,

thus permitting the contents of the vessel 5 to be discharged. When thetank 17 by the use of water therefrom becomes partially emptied, thefloat l9 descends and through the instrumentality of the cord 20* causesthe lever 12 to release the dog 10 from the weight vessel 5 andthereupon the vane or controlling element of the wind mill againoperatesby its own weight to throw the wind mill before the wind and intooperative condition and in so doing raises the vessel 5 and starts thepump in operation. Hence, my improved stopping and starting mechanismautomatically controls the operation of the wind mill and keeps the tank17 supplied with a desired quantity of water.

While I have herein shown and described a preferred form of myinvention, I would have it understood that changes may be made in theform, proportion and construe tion of the several parts withoutdeparting from the spirit of the invention and within the scope of theappended claim.

I claim In combination with a wind mill having a controlling element, apump operated by the wind mill, and a tank supplied by the pump, a floatin the tank, a vertically movable weight vessel connected to thecontrolling element of the wind mill and raised thereby when the windmill is in operation,

said weight vessel having a normally closed and released by the floatwhen the level of 10 discharge valve, an overflow pipe leading the waterin the tank is lowered. from the tank and arranged to discharge Intestimony whereof I afiix my signature into the weight vessel, means toopen the in presence of two witnesses.

valve of the weight vessel when the latter is JAMES F SMITH in a loweredposition, and locking means for the Weight vessel to hold the same inWitnesses: lowered position, the said locking means be- P. M. PEIROE,ing connected to and operated by the float J. L. MEAD.
